[Elecraft] RTTY issue (OT?)

[Jim Brown]

I prefer 915 Hz tones, and I ran into the same problem. I learned that 
there are several things I needed to change. First is to change the HAM 
default. This will work fine, UNTIL you choose another decoding 
algorithm, like Flutter, and MMTTY will switch back to 2125 Hz.

To really solve this, you need to edit the USERPARA.INI file. With MMTTY 
NOT running, open file with Notepad, Search and Replace 
DefMarkFreq=2.125000e+03  with DefMarkFreq=1.275000e+03, and save the file.

When you restart MMTTY, make sure that 1275 Hz is set, and also that the 
HAM Default is is 1275 Hz.
